Encapsulation mold

Abstract

An encapsulation mold is provided, which may include an upper mold, a lower mold and a clamping device. The clamping device includes a rubber anti-slip block fixed to a joint surface of the upper mold, and a rubber anti-slip block fixed to a joint surface of the lower mold, wherein both of the rubber anti-slip blocks can fix the glass tightly. Therefore, after the upper mold and the lower mold are pressed against each other, these rubber anti-slip blocks may deform and apply a couple of forces having opposite directions to the glass. Under this couple of forces, the glass can be completely fixed in the encapsulation mold, which can avoid glass to be crushed caused by glass moving during injection molding. Meanwhile, because these rubber anti-slip blocks are elastic, they can play an anti-slip role and prop the glass, which may prevent the glass 40 from breakage.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to Chinese patent application No. 201220577801.0, filed on Nov. 5, 2012, and entitled “Encapsulation Mold”, the entire disclosure of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure generally relates to an encapsulation mold for encapsulating glass.BACKGROUND OF THE DISCLOSURE[0003]Encapsulated glass is one kind of safety glass, which is widely used in automobiles as front windshield glass, rear windshield glass, skylight glass or quarter window glass. Encapsulated glass may have the following advantages: 1, encapsulated glass can be bonded to a car body tightly, which guarantees sealing of the car; 2, glass is combined with encapsulating plastics in one piece, which makes it easy to install, thereby shortening the installation cycle and improving the production efficiency; meanwhile, encapsulated glass may have different types of cross section, which can be desi...

AI Technical Summary

Benefits of technology

The present disclosure provides an encapsulation mold for manufacturing encapsulated glass to solve problems of easy crushing. The mold includes an upper mold, a lower mold, and a clamping device with rubber anti-slip blocks. The rubber anti-slip blocks have surfaces for clamping the glass, and apply a pair of forces with opposite directions to the glass, preventing breakage during injection molding. Additionally, the rubber anti-slip blocks compensate for the curvature tolerance of the glass, making the mold suitable for glasses from different batches. For glasses with a big size, the clamping device includes more rubber anti-slip blocks, with some of them having rubber bumps to reduce the breakage rate of the glass.

Problems solved by technology

While injection molding is performed on the toughened glass, the toughened glass may move under huge impacts, which in turn causes the toughened glass to be crushed or scratched.

Especially, when the glass 1 has a big size, a central region of the glass 1 may have a very large curvature tolerance, which may result in high breakage rate of the glass.

As a result, the glass is not easily to be crushed even if the glass of a big size has a great curvature tolerance.
